Abstract
The utility model relates to a bladeless fan, which comprises a base. A rotary fan main body is arranged on the base. A fan assembly is fixedly installed inside the fan main body. An air inlet communicated with the fan assembly is arranged on the fan main body. An annular sleeve with a center air channel is installed at the top end of the fan main body. The annular sleeve is horizontally arranged at the top end of the fan main body. Two sides of the annular sleeve corresponding to the center air channel form a center air channel inlet and a center air channel outlet. The thickness of the lateral wall of the annular sleeve is reduced gradually from the center air channel inlet to the center air channel outlet. Furthermore, a cavity in the lateral wall is communicated with the fan assembly. The inner wall of the annular sleeve close to the center air channel inlet is provided with an air outlet corresponding to the air inlet. An arc transition is arranged on the inner wall of the annular sleeve which extends outward from the center air channel inlet. The bladeless fan effectively improves air speed and is simple in structure and remarkable in effect.
Description
Technical field
The utility model relates to no blade fan field, especially a kind of no blade fan with the effect of reinforcement fluid wind speed.
Background technique
At present, traditional unemployed fan, its annular fan head has fluid and passes through the air channel; And fluid generally gets into by the less end in air port, and behind the air channel, an end bigger by the air port blows out; Its benefit is that the area of diffuse fluid is bigger; But its defective is a fluid, and to blow out its flow velocity of back by the bigger end in air port low, and the blowing distance is short, is unfavorable for long apart from the cooling of environment canyon etc.
Summary of the invention
The purpose of the utility model is to solve the deficiency of above-mentioned existing technology, and provides a kind of simple and reasonable for structure, effectively improves the no blade fan of wind speed.
The utility model solves the technological scheme that its technical problem adopted: a kind of no blade fan, comprise base, and base is provided with rotating blower fan main body; Blower fan main body internal fixation is equipped with fan assembly, offers the intake grill that communicates with fan assembly on the blower fan main body, and blower fan main body top is equipped with the annulus in air channel, band center; It is characterized in that; Said annulus is horizontal type and is arranged on blower fan main body top, and the annulus both sides in air channel, corresponding center constitute the air channel, center to be gone into, export, and the sidewall thickness of annulus is communicated with fan assembly toward the cavity that center ducting outlet direction is in minimizing gradually and the sidewall by air channel, center inlet; Said annulus inwall near air channel, center inlet is provided with and the corresponding exhaust outlet of intake grill; The annulus inwall that air channel, center inlet extends outward is provided with arc transition, and the no blade fan of this structure is because the annulus inwall that air channel, center inlet extends outward is provided with arc transition; Be the maximum diameter of the maximum diameter of ingress, air channel, center greater than center ducting outlet place; The distinguished and admirable body of big flow is got into by air channel, center inlet, after pushing gradually through the air channel, center, is got rid of by the center ducting outlet; Effectively improve the wind rate of flow of fluid, it is simple in structure, effect is obvious.
The utility model can also adopt following technical measures to solve: as improvement further; The horizontal pivot angle seat that rotates along base is installed on the said base; The seat that the blower fan main body is adjustable blowing angle is located on the pivot angle seat; The blower fan main body can be made horizontal hunting along horizontal pivot angle seat, to regulate the blowing angle, improves the use flexibility.
On blower fan main body top, dismounting is easy to connect through movable buckle holding for said annulus.
The ducting outlet direction is minimizing gradually to cavity thickness in the sidewall of said annulus toward the center by air channel, center inlet.
The beneficial effect of the utility model is: the no blade fan of the utility model, and it is simple and reasonable for structure, because the annulus inwall that exhaust outlet extends outward is provided with arc transition; Be the maximum diameter of the maximum diameter of ingress, air channel, center greater than center ducting outlet place, the distinguished and admirable body of big flow is got into by air channel, center inlet, after pushing gradually through the air channel, center; Get rid of by the center ducting outlet; Effectively improve the wind rate of flow of fluid, prolong the blowing distance, it is simple in structure, effect is obvious.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
As shown in Figure 1; A kind of no blade fan; Comprise base 1, base 1 is provided with rotating blower fan main body 2, and blower fan main body 2 internal fixation are equipped with fan assembly 3; Offer the intake grill 4 that communicates with fan assembly 3 on the blower fan main body 2; Blower fan main body 2 tops are equipped with the annulus 6 in air channel, band center 5, it is characterized in that, said annulus 6 is horizontal type and is arranged on blower fan main body 2 tops; Annulus 6 both sides in air channel, corresponding center 5 constitute the air channel, center and go into, export 7,8; Sidewall 601 thickness of annulus 6 are communicated with fan assembly 3 toward the cavitys 602 that center ducting outlet 8 directions are in minimizing gradually and the sidewall 601 by air channel, center inlet 7, and said annulus 6 inwalls 603 near air channel, center 5 inlets are provided with and intake grill 4 corresponding exhaust outlets 9, and annulus 6 inwalls 601 that air channel, center inlet 7 extends outward are provided with circular arc 10 transition.
The no blade fan of this structure, because annulus 6 inwalls 601 that air channel, center inlet 7 extends outward are provided with circular arc 10 transition, promptly the air channel, center enters the mouth the maximum diameter at 7 places greater than the maximum diameter at center ducting outlet 8 places; The distinguished and admirable body of big flow is got into by air channel, center inlet 7; After pushing gradually through air channel, center 5, get rid of, effectively improve the wind rate of flow of fluid by center ducting outlet 8; Prolong the blowing distance, it is simple in structure, effect is obvious.
As improvement further; The horizontal pivot angle seat 11 that rotates along base 1 is installed on the said base 1, and the seat that blower fan main body 2 is adjustable blowing angle is located on the pivot angle seat 11, and blower fan main body 2 can be made horizontal hunting along horizontal pivot angle seat 11; To regulate the blowing angle, improve the use flexibility.
On blower fan main body 2 tops, dismounting is easy to connect through movable buckle 12 holdings for said annulus 6.
Above-described specific embodiment is merely the utility model preferred embodiment, the equivalent arrangements of being done according to the utility model claim such as, and the technology that all should be the utility model contains.
